DI Helen Grace

Caught in a wicked game of cat and mouse, Detective Helen Grace finds herself trapped among the hunted in the darkest thriller yet from the international bestselling author of Little Boy Blue and Eeny Meeny.
 
Framed for a murder she didn't commit...
 
As one of HM Prison Holloway's most high-profile new inmates, Helen Grace has a target on her back and nowhere to hide. She has made a long list of enemies over the course of her career—some are incarcerated within these very walls. When one of Helen's fellow prisoners is found mutilated and murdered in her own locked cell, it's clear that the killer is someone on the inside.
 
But time is running out for Helen as she races to expose the person who framed her, and the body count in the prison starts to climb. Helen will need to draw on all her investigative skills and instincts to catch the serial killer behind these murders and discover the truth—unless the killer finds her first.
